OEM Part Number: confirm via VIN — radiator grille (aftermarket) Diederichs 1080340

Accuracy note: Covers the Audi A1 (8X 2010-2018) as listed in the UK aftermarket catalogues. Grilles are sold by trim and facelift, and many generations had different grilles for base, mid and top trims, with or without a radar or camera opening. Where the catalogue splits a grille into left and right or upper and lower sections, buy both halves if both are damaged. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives; carmakers rarely publish the genuine number against these, so match a genuine grille against your VIN if you want a guaranteed fit.

Audi A1 Grille: Cosmetic on the Surface, Functional Underneath

The front grille on the Audi A1 does more than shape the car's face — it manages airflow to the radiator and, on many modern cars, houses or surrounds sensors for adaptive cruise control or parking assistance, meaning the correct part depends on more than just how it looks.

Before you buy: grille design varies significantly by trim, and higher trims may integrate radar or camera sensors behind or within the grille itself. Always confirm against your VIN before ordering.

Audi A1 Grille: What It Does

Beyond styling, the grille on the A1 directs airflow to the radiator and, on trims equipped with adaptive cruise control, may house or sit directly in front of the radar sensor used for that system. A grille that looks compatible but lacks the correct sensor cutout can interfere with these systems even if it fits physically.

A Genuinely Useful Piece of Context Worth Knowing About Radar Sensor Faults — Audi A1 Grille

If the adaptive cruise control has become unavailable, this is genuinely worth knowing before assuming the whole sensor needs replacing: the radar sensor contains an internal heater unit on related Audi models, and this specific heater has been documented failing on its own, with the main sensor remaining fine.

A genuinely important clarification worth knowing about fault codes: a specific diagnostic code referring to the sensor being misadjusted or incorrectly positioned does not automatically mean a new sensor is required — it may simply need proper recalibration by a dealer.

It's also genuinely worth knowing that removing the front bumper for entirely unrelated work has been documented damaging the radar units or their wiring in the process on related models.
